No. 826,474 A Application filed December provide an improved construction of simple and inexpensive character, not readily tampered with, andprotected from the weather, while securing a retarded or step-by-step movement in' throwin on-the current and permitting the mechanism to be turned back 'to' the initial position to'throw off the cur"- rent without retardation.

In the accompanying drawings, Figure, 1 is a sectional elevation representing a form of the invention. Fi 2 isja sectional view of details of construction, taken transversel to the section shown in Fig .1'.

nections. Fig. 4 is a vertical'sectional view representing a second form of the-invention and Fig. 5 is a sectional view of a art of the construction shown in -Fig. 4, ta en transversely theretof As shown in the drawings, the controller,

the casing-top 2, has fixedthereon a cy indrical hood 3, which is engaged and revolved by the handle 4. As shown in Fig s. 1,-2, and 3, peripheral lugs or stops 5 are ormed at proper ntervals within the hood, and depending from the top. of the hood, between the center and the pe-v riphery,-are fingers 6, pivoted by means of pintles 7 passing therethrough and through the supporting-lugs gers have the tops thereof provided with the rounded portions 9 and th 10, by which they are permitted to oscillate freely in one direction from the vertical sition, in which they normally hang, w 'le 'they'are prevented'from oscillating substan tially beyond the vertical position in the other direction, the lower arts'of the respec-. tive fingers being suitab though not es- Specification f Letters Patent.

sentially, provided with the inclined surfaces 11 on the opposite sides of the centers of oscillation from theshoulders 10.

Fixed to-the top of the casing 2 is a bear-- CDMPANKOF PHILADELPHIA, PENN- ing 12, upon which is fulcrumed intermediate of its length a dog 13 by means of the pintle 14, theouter end of the dog in its normal osition being held down by gravity beneat the stops 5 and the inner end being up in'the path of the fingers 6.

When the handle is revolved to revolve the hood and the shaft for the purpose of turning on current, the fingers 6 successively envgage theinner end of the dog (suitably pro- .vided with'the inclined contact-surface 6 and-tilt it so that the outer end lies in the path of the stops 5. Each fingertilts the dog so that it is engaged by-the advancing stop corresponding thereto to checkthe rotittlOH', and the dog drops out of engagement with the stop when the pressure on the handle is released, the successiveactions com- 'pelling a regulated or step-by-step forward movement. In the reverse movement, the fingers-swing back, riding over the end of the 0g in-their path, and the mechanismis re-- versed without-engagement of the sto s or retardation, the outer end of the dog eing suitably provided with 6", whereby a ositiv'e enga ement cannot-be he stops in t e reverse movement.

"part of the hood is provided with the interior ange or ring 15 and the inclined fingers 16, fulcrumed on the pintles or bearings 17, the

free ends of the-fingers normally resting on the flange, from which such fingers are inclined upwardly in the direction of the corresponding stops or lugs 5. Fixed to the to 2 is a bearing 18, in which is fulcrumed a 0g 19 by means of a pintle 20. This dog has its free end resting normally on the ring 15, its outer end with the inclined surface 19 riding up the fingers into engagement with the turning on the current,'while resting on the flange and having the fingers pass over it in thereverse movement; As in turning on 'the current the dog is engaged by.- the successive inclined finger of the revolving hood and carried up the inclined planes thereof, so that it is engaged by the corresponding stops,

:Iaving described my invention, I clai1n- 1. A controller-regulator comprising, in combination with the controller-shaft, a revolving device fixed to said shaft and having thereon stops'and fingers mov'able relatively to said stops, in combina with an Oscillating dog having a stationary support.

2. A controller-regulator comprising a re volving hood having stops and fingers de pending therefrom, in combination with a fulcrumed dog thrown by said lingers into the path of said stops.

3. A controller-regulator comprising, in combination with a controller casing and shaft, a hood fixed to said shaft and having sto s and fingers thereon, a bearing fixed to sai casing, and a dog iulcrumed on said bearing, said dog being tilted by said fingers to engage said stops.

4. A controller-regulator comprising, in combination with a stationary part and a re volving shaft, a hood fixed to-said shaft, said hood having fixed stops and fulcrumed fingers therein, and a dog having a'fulcrumed connection with said stationary part, said dog automatically disen aging said stops.

5. A controller regu iator comprising a hood, a series of stops, a series of oscillating fin ers having a free motion in one direction other, and an oscillating dog thrown by said fingers into engagement with said stops in turning on the current and freely passing said fingers in turning off the current, said (log be- 6. Acontroller-regulator com risinga 0g fulcrumed intermediate of its ength, a series of stops and a series of fingers, said fingers engaging one end of said dog to throw the other end thereof into the path of said stops.

7. fulcrumed intermediate of its ength, a series of stops, 9. series of fin ers engaging one end of said dog to throw the other end into the path of said sto s, said dog being automatically disenga e from said stops.
